Job Description and Requirements

We Are

Synopsys is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products. We deliver industry-leading silicon design, IP, simulation and analysis solutions, and design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow.


You Are

You bring extensive experience operating mission-critical infrastructure services in complex, large-scale environments. Your expertise spans LDAP directory services, DNS, SMTP, DHCP, and Unix-based systems, and you have consistently delivered high availability across distributed architectures.

You approach infrastructure with a focus on automation, observability, and operational excellence. You design solutions that account for failure modes and long-term maintainability. Your technical leadership extends to incident management, root cause analysis, and cross-functional collaboration with Engineering, Security, and Cloud teams.

At Synopsys, you will own the infrastructure services that underpin daily operations for 30,000 employees globally.


What You'll Be Doing

  • Own the reliability, availability, and operational health of LDAP, SMTP, DNS, DHCP, and other Unix-based infrastructure services.
  • Manage day-to-day operations, incident response, troubleshooting, performance tuning, and capacity planning.
  • Lead infrastructure projects, including solution design, deployment, upgrades, and service modernization.
  • Drive automation through scripting and configuration management to improve efficiency and scalability.
  • Design and maintain highly available, secure, and resilient infrastructure across on-premises, cloud, and hybrid environments.
  • Implement monitoring, alerting, and observability practices to improve service reliability and operational visibility.
  • Partner with cross-functional teams on enterprise initiatives and provide technical leadership for infrastructure services.
  • Develop operational standards, documentation, and best practices.


The Impact You Will Have

  • Directly improve uptime and reliability for directory services, email, DNS, and network services that support engineering workflows across Synopsys globally
  • Reduce incident frequency and mean time to recovery by identifying root causes, implementing fixes, and automating responses to known failure patterns
  • Accelerate infrastructure delivery timelines by replacing manual processes with repeatable, version-controlled automation
  • Increase operational visibility by building monitoring and alerting that catches problems before users notice
  • Enable secure, scalable infrastructure growth by designing solutions that work across on-premises data centers, Azure, AWS, and Google Cloud Platform
  • Raise the technical bar for the team by mentoring engineers, sharing knowledge, and setting standards for how infrastructure services should be built and operated
  • Free up team capacity by eliminating repetitive manual work, allowing engineers to focus on higher-value projects and service improvements


What You'll Need

  • 8+ years of hands-on experience in site reliability, infrastructure engineering, or Unix/Linux systems administration, with a track record of owning production services at scale
  • Strong working knowledge of LDAP directory services such as Oracle Unified Directory, OpenLDAP, 389DS, or Red Hat Directory Server, including architecture, replication, and troubleshooting
  • Strong working knowledge of Postfix SMTP including architecture and troubleshooting.
  • Strong working knowledge of DNS technologies like BIND, Unbound, Anycast, DHCP services in production environments including architecture and troubleshooting. Knowledge of Infoblox or similar IPAM solutions is a plus
  • Proven ability to automate infrastructure using Ansible, shell scripting (Bash, Korn Shell), and cron-based job scheduling
  • Experience designing and implementing monitoring, alerting, and observability solutions that provide actionable insights into service health
  • Hands-on experience with cloud platforms including Azure, AWS, or Google Cloud Platform, and the ability to operate infrastructure across hybrid environments
  • Strong incident management skills, including troubleshooting complex distributed systems, performing root cause analysis, and leading post-incident reviews


Who You Are

  • You demonstrate strong leadership during critical incidents, rapidly assessing system failures, coordinating response efforts, and driving resolution while maintaining clear communication with stakeholders
  • You develop automation and infrastructure code with maintainability in mind, ensuring documentation and implementation clarity that enables team members to support and extend your work
  • You communicate complex technical concepts effectively across organizational levels, translating infrastructure challenges into clear business context for leadership and detailed guidance for engineering teams
  • You take a systematic approach to problem resolution, investigating underlying causes rather than addressing symptoms, and implementing preventive measures to improve long-term system stability


The Team You'll Be Part Of

You’ll join a collaborative engineering team responsible for delivering reliable, secure, and scalable enterprise infrastructure services. You’ll work alongside experienced engineers and cross-functional teams to improve service reliability, expand automation and observability, modernize infrastructure, and solve complex technical challenges. Our culture emphasizes technical ownership, collaboration, knowledge sharing, and continuous improvement.


Rewards and Benefits

We offer a comprehensive range of health, wellness, and financial benefits to cater to your needs. Our total rewards include both monetary and non-monetary offerings.


#LI-Remote

At Synopsys, we want talented people of every background to feel valued and supported to do their best work. Synopsys considers all applicants for employment without regard to race, color, religion, national origin, gender, sexual orientation, age, military veteran status, or disability.
